Here is switchMap use case: Rx.Observable.of('some_url') .switchMap(url => this.http.get(url)). In this example Observable produces an URL string, after that http service is invoked with this URL. 27 Jan 2015 the switchMap is like the flatMap BUT it will only emit items from the new observable until a new event is emitted from the source observable. The marble diagram shows it well. Notice the difference in the diagrams: In switchMap the second original emission (green marble) does not emit its second mapped 27 Jan 2015 the switchMap is like the flatMap BUT it will only emit items from the new observable until a new event is emitted from the source observable.

TBD //emit immediately, then every 5s const source = Rx.Observable.timer(0, 5000); //switch to new inner observable when source emits, emit items that are emitted const example = source.switchMap(() => Rx.Observable.interval(500)); //output: 0,1,2,3,4,5,6,7,8,90,1,2,3,4,5,6,7,8 const subscribe = example.subscribe(val 5 May 2017 probably the first operator that we come across that is not part of the Array API but still very frequently used is the RxJs switchMap operator. Let's see how this operator works by going over its behavior in a couple of very common situations: short-lived streams like for example HTTP Requests, that only emit 29 Mar 2017 switchMap and mergeMap are probably going the be the most powerful and frequently used operators in your arsenal. mergeMap(function (x) { return Rx.Observable.interval(500).take(3).map(y => `${x}:${y}`) }); source.subscribe(d => console.log(d)); Marble diagram Tags: reactive programmingrxjs. 12 Jan 2015 map( ) — transform the items emitted by an Observable by applying a function to each of them; flatMap( ) , concatMap( ) , and flatMapIterable( ) — transform the items emitted by an Observable into Observables (or Iterables), then flatten this into a single Observable; switchMap( ) — transform the items Understand switchMap. This has absolutely no scientific basis, but I will contend this: Understanding switchMap is an essential step on the path to using RxJava effectively. Upon understanding this operator, you will find use cases for it everywhere. Furthermore, using it opens the door to using a wide variety of other helpful 14 Jun 2017 In this article, I am going explain the difference between map, concatMap, flatMap and switchMap operators.
